Summary

Basal encephaloceles extending into the sphenoid sinus represent a distinct subgroup. Rhinorrhea is the primary symptom, and surgical treatment involves a midline approach with shunting.

Area of Science:

  • Neurosurgery
  • Otorhinolaryngology
  • Radiology

Background:

  • Basal encephaloceles are currently classified with transsphenoidal encephaloceles.
  • Encephaloceles limited to the sphenoid sinus may constitute a unique clinical entity.

Observation:

  • A review of one personal case and six literature cases was conducted.
  • The personal case presented with an empty sella turcica.
  • Rhinorrhea was the most consistent initial clinical sign across reviewed cases.

Findings:

  • Encephaloceles confined to the sphenoid sinus appear to be a rare subgroup of sphenoidal encephaloceles.
  • Associated intracranial anomalies are infrequently observed.
  • The primary presenting symptom is typically rhinorrhea.

Implications:

  • Reclassifying these specific encephaloceles may improve diagnostic accuracy.
  • Early identification of rhinorrhea is crucial for diagnosis.
  • An extradural transsphenoidal or transethmoidal midline approach with shunting is the recommended surgical treatment.
